"For verily I say unto you," This is Jesus talking. "That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith." (Mark 11:23)
Usually, a mountaintop experience is seen as something holy, special. Something rare and valuable. It refers to the transfiguration experience of Jesus with Peter and John (see Luke 9). And while the Bible portrays mountains in this positive light, by and large, sometimes mountains must be removed, no way around it. Big words to be sure and until you get there God may well allow you to experience the scale and scope of a problem before he will remove it for you. That way, you'll be able to appreciate some of what it took for God to get you through.
"He maketh my feet like hinds' (deer) feet, and setteth me upon my high places...Thou has enlarged my steps under me, that my feet did not slip." (Psalm 18:33, 36)
Mount Hermon, on the border between Syria and Lebanon, is over nine-thousand feet high. Contrast that with Mount Tabor in Galilee at nearly two-thousand. It doesn't matter the size of the problem, unless you attempt to scale it, you won't know what you're in for. Think about it. Forgive me if you think this contradicts what Jesus said about speaking to the mountain—your problem. And while "scalability" generally connotes "climb-ability"—the mountain's, that is, it also means the ability to grow larger. I don't mean to go around in circles, but which is bigger. Your faith? Or the mountain in your way? Which is more scalable? There's only one way to find out (or is there?).
"Who art thou, O great mountain? Before Zerubbabel thou shalt become a plain: and he shall bring forth the headstone thereof with shoutings, crying, Grace, grace unto it." (Zechariah 4:7)
The word "tramontane" refers to "that which comes from the other side of the mountains". You don't know how, you don't know why, but you know that the mountainous obstacle in your way keeps you from getting there. Think of the yearly pilgrimage the Jews took to Jerusalem. They traversed the mountains and sidled along narrow, rubble-strewn paths in order to get to their desired destination. "I will lift up mine eyes unto the hills, from whence cometh my help? My help cometh from the Lord, which made Heaven and earth. He will not suffer thy foot to be moved..." (Psalm 121:1-3)
And they got there eventually.
But what about what Jesus says regarding the moving of said mountains? Because He will move it for you. There is another way of looking at this.
"In the Lord put I my trust: how say ye to my soul, Flee as a bird to your mountain?" (Psalm 11:1)
The deng birds of Buddhist myth were so large as to remove mountains with a single wingbeat. Like, country sized. That's not fair. Where is the glory due God when we get so high and full of ourselves and think we're the ones who obtained the victory? "If God doesn't do it all, He wants nothing to do with it." I remember my dad saying this and it's true. Sometimes, God simply has us observe and report. To "watch and pray" (Mark 13:33) as it were.
"O sing unto the Lord a new song; for he hath done marvelous things: His right hand, and His holy arm hath gotten Him the victory." (Psalm 98:1)
"And Moses said unto the people, Fear ye not, stand still, and see the salvation of the Lord, which He will shew you today" (Exodus 14:13)
Though Moses was speaking of an impending threat (the Egyptian army, led by Pharaoh himself), the mountain looms large and immobile. Stuck in your path. And some peaks are impassable. You'd be struggling for breath on Hermon's peak. So what to do? Speak to it. Pray against it. Go about your business at base camp and watch God sweep it away in one fell swoop. It might take time, it might take effort. But the effort you expend in fighting it with faith would be the same as you trying to scale it. Your faith will grow either way. It's just a matter of knowing which is which. And deng birds have nothing on your faith.
"And every island fled away, and the mountains were not found." (Revelation 16:20, emphasis mine)
It's gonna happen one way or the other.
